The former X Factor star has since moved back to the UK with her new husband, comedian Brian Moote - who she tied the knot with last October - and is now living in the Celebrity Big Brother house.

Seeming a world away from her former X Factor days, Katie told CBB host Emma Willis that she's thrilled to be back in the UK.

"It’s so great to be back in England! Yes, finally!" she said.

“I think I’ve grown up I guess. I’m married now; it’s a big new chapter in my life. I’m just so excited for this adventure, no lie. I can’t wait to get involved in the tasks, we’re fearless here – throw me in.”
